I would change the narrative just a touch. You still need to build a team. One guy cannot completely just do it all by himself.
KC's defense played well this year to keep them in games to give Mahomes a chance to do his thing. On offense, they still had Kelce as a game changer for Mahomes. Eventually Rice emerged at WR and Pacheco kept the running game efficient for them. Their OL did just enough.
The narrative I believe is that you have to take the elite playmakers especially at the key positions like at QB when you have the opportunity. You cannot pass up your chance at Elite because those chances just don't come very often.
But yes, you should always strive to build a team that has elite or at least above average talent at every position. I imagine that is the goal of any GM. However, the reality is that is damn near impossible to achieve. Age, injuries, contracts, the CAP, are all going to be working against that. IMO, the reality is that you have to find a core of blue chip playmakers that you can keep together. For sustained success and real shots at a championships, one of those blue chip core players -has- to be the QB.
If you do not currently have an elite/blue-chip QB, and you think you have a real shot at an elite QB to put in your core, then you have to take that chance. Then you keep building around that guy and hopefully go win a Superbowl or three.
